Diversity metric for evaluation of quantum annealing
Alex Zucca, Hossein Sadeghi, Masoud Mohseni +1
Solving discrete NP-hard problems is an important part of scientific discoveries and operations research as well as many commercial applications. A commonly used metric to compare…
Generalized Brans-Dicke theories in light of evolving dark energy
Alex Zucca, Levon Pogosian, Alessandra Silvestri +2
The expansion history of the Universe reconstructed from a combination of recent data indicates a preference for a changing Dark Energy (DE) density. Moreover, the DE density appea…
MGCAMB with massive neutrinos and dynamical dark energy
Alex Zucca, Levon Pogosian, Alessandra Silvestri +1
We present a major upgrade of MGCAMB, a patch for the Einstein-Boltzmann solver CAMB used for phenomenological tests of general relativity against cosmological datasets. This new v…
Observational Constraints on Constant Roll Inflation
Jose T. Galvez Ghersi, Alex Zucca, Andrei V. Frolov
Constant-roll inflation was recently introduced by Motohashi, Starobinsky and Yokoyama as a phenomenological way to parametrize deviations from the slow-roll scenarios. In this pap…
Evolution of dark energy reconstructed from the latest observations
Yuting Wang, Levon Pogosian, Gong-Bo Zhao +1
We reconstruct evolution of the dark energy (DE) density using a nonparametric Bayesian approach from a combination of latest observational data. We caution against parameterizing…
Unscreening scalarons with a black hole
Andrei V. Frolov, José T. Gálvez Ghersi, Alex Zucca
It is typically believed that the additional degrees of freedom in any modification of gravity are completely suppressed by the large energy densities coexisting with an astrophysi…
